Try with AssetCategoryLocalServiceUtil and article.getId() in place of getArticleId

this is the right way:
List<AssetCategory> categories = AssetCategoryLocalServiceUtil.getCategories(JournalArticle.class.getName(), article1.getResourcePrimKey());

Hello everybody,

I am trying to get the category from a webcontent article using exactly the way u show here :

List<assetcategory> categories = AssetCategoryLocalServiceUtil.getCategories( JournalArticle.class.getName(), oneArt.getResourcePrimKey() );</assetcategory>

But I always get an empty list.

I assign the category (actually I can only select one, so it is a bit curious that above method returns a list ;))) by using Content->Web Content -> Categorization and then selecting News from the Select-Box.

So - am I using liferay wrong? Is it the wrong usage of API? Or is it a bug? ;)

Thanks a lot!

Regards, Heiko

Hi,

I think above code shall give you entire information of categories associated with article.

You can try below code, which gives categoryNames:


String[] categoryName = AssetCategoryLocalServiceUtil.getCategoryNames(JournalArticle.class.getName(), 13607); // replace with your classPK
System.out.println(Arrays.toString(categoryName));

It seems Heiko talking about web content type under categorization section - you are speaking about categories/tags related pop up

Thanks Nagendra, thanks Manali for ur help. Nagendra, you are totally right - and with the help of ur example it works now using a Dynamic Query instead of trying to filter it on the fly!

Heiko,

I think here solution is for asset category selector - they are referring to pop up of categories which is near tags. Not the journal article's type - news/test.

I didn't find one direct method to get articles by type.

You can give it a try with one of search overloaded methods. One more option is dynamic query ( these you can try with JournalArticleLocalServiceUtil). Another have a look at AssetEntryQuery.

You shouldn't capture other peoples old threads. your question is different then the thread topic.
You could use AssetEntryLocalService.clearAssetCategoryAssetEntries(long categoryId) to delete all of them or fetch a list of entries getAssetCategoryAssetEntries, iterate through it and remove only some of them. Depends on your usecase.
